When limiting the compressor casing, the position of the sliding plate 3 can be adjusted by manually moving the movable rod 112 to drive the sliding plate 3 to move, and then the limit plate 111 is moved on the movable rod 112 to the clamping limit groove 10 to limit the sliding plate 3. Then, the compressor casing can be moved to the cargo box 2 to fix it, so that it can adapt to compressor casings of different lengths, thereby improving the scope of use of the device and having strong practicality.

[0025] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, the movable limit assembly 11 also includes a clamping rod 114, a first movable groove is provided in the limit plate 111, the clamping rod 114 is slidably connected to the first movable groove, a spring 115 is fixedly connected between the top of the clamping rod 114 and the inner wall of the first movable groove, a sliding groove 14 is provided at the top of the movable rod 112, and clamping grooves 13 are provided on both sides of the sliding groove 14. When the movable rod 112 is manually moved, the clamping rod 114 is clamped in the clamping groove 13 on the side away from the cargo box 2, thereby limiting the limit plate 111. , to prevent it from deviating when the moving rod 112 moves. When the moving rod 112 moves to the specified position, the limit of the limit plate 111 is released by moving the clamping rod 114, and then the limit plate 111 is moved into the clamping limit groove 10 to limit the moving rod 112. The clamping rod 114 is driven by the spring 115 to clamp into the clamping groove 13 close to the side of the cargo box 2 to limit the limit plate 111 and prevent it from deviating. This structural design is convenient for stably limiting the moving rod 112 and has good practicality.

[0026] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, an adjusting rod 116 is fixedly connected to one side of the top of the clamping rod 114, and an adjusting groove is provided on the outer wall of the limiting plate 111 away from the clamping limiting groove 10.

In response, after adjusting the position of the sliding plate 3, the compressor casing is placed between the first rolling clamping assembly 6 and the second rolling clamping assembly 8. When the second rolling clamping assembly 8 is adjusted by the driving assembly 9 to fix the compressor casing, the first rolling clamping assembly 6 is driven by the first telescopic rod 7 to fix the compressor casing. In this way, the compressor casing can be conveniently fixed, which is easy to use, saves the staff's time in fixing the compressor casing, and improves work efficiency. The driving assembly 9, the first rolling clamping assembly 6 and the second rolling clamping assembly 8 are all existing technologies and will not be elaborated on here.

[0028] In this embodiment, if Figure 1 As shown, a first baffle 4 is fixedly connected to the center of the top of the carrying box 2 away from the second receiving slot. The arrangement of the first baffle 4 facilitates the rapid installation of the compressor housing and is highly practical.

After the compressor casing is fixed, it is limited by the second baffle 121 to prevent its position from shifting when it is rotated under the drive of the first rolling clamping assembly 6 and the second rolling clamping assembly 8. A plurality of balls 5 are rotatably connected at equal distances at one end of the first baffle 4 and the second baffle 121 that are close to each other.

When the second baffle 121 moves to the specified position, the second telescopic rod 125 is driven to retract by pushing the rotating plate 124 so that the locking gear 123 engages with the locking tooth sleeve 122, thereby limiting the second baffle 121 to prevent it from deflecting.

[0032] Working principle: When in use, first manually move the moving rod 112 according to the length of the compressor housing to drive the sliding plate 3 to move. When the sliding plate 3 moves to the specified position, the adjusting rod 116 can be moved vertically in the adjusting groove to drive the clamping rod 114 to move in the clamping groove 13 to release the limit of the limit plate 111. Then, the limit plate 111 is moved on the moving rod 112 to the clamping limit groove 10. The clamping rod 114 moves in the sliding groove 14 to the top of the clamping groove 13. The clamping rod 114 is clamped in the clamping groove 13 near the side of the cargo box 2 under the drive of the spring 115 to limit the limit plate 111. Then, one end of the compressor housing is close to the first gear. The plate 4 is placed, and then the first rolling clamping assembly 6 is driven by the first telescopic rod 7 to fix the compressor casing by adjusting the second rolling clamping assembly 8 through the driving assembly 9. Then, the rotating plate 124 is rotated to drive the second telescopic rod 125 to rotate, which drives the gear 126 to rotate, thereby driving the rack 127 to move, driving the second baffle 121 to rise and fit the other end of the compressor casing, and then pushing the rotating plate 124 to drive the second telescopic rod 125 to shrink so that the locking gear 123 is engaged with the locking gear sleeve 122. The utility model can adapt to compressor casings of different lengths, improves the scope of use of the device, and is highly practical.
